Seawalls are constructed with a variety of materials, each featuring unique characteristics and benefits. Some of the most common types of seawalls include:
These seawalls are made of poured concrete and are a popular choice due to their durability and strength. Concrete seawalls are often used in areas with strong wave action or heavy boat traffic.
Sheet Pile Seawalls
These seawalls are made of interlocking sheets of metal, vinyl, or composite that are driven into the ground. Sheet pile seawalls are typically used in areas with softer soil or where the water level is expected to fluctuate.
Rock seawalls (a.k.a. Rip Rap) are made of large, heavy stones that are placed along the shoreline to create a barrier. Rock seawalls are often used in areas with strong wave action or to provide a natural-looking barrier.
Wooden seawalls are typically the least expensive to construct. They are most often used in residential applications. Wooden seawalls tend to have the shortest lifespan of all the seawall types profiled in this article.
In conclusion, seawalls are critical structures that serve a variety of practical functions for waterfront property owners and other stakeholders. There are several types of seawalls to choose from. Once installed, is important to work with a skilled and experienced contractor to ensure proper maintenance and repair.
